>> pelley: con men used to travel town to town hawking medical remedies said to be made of chinese snakes. snake oil was useless and dangerous. so the f.d.a. was created to put a stop to it and other food and drug scams. but today, quack medicine has never been bigger. in the 21st century, snake oil has been replaced by bogus therapies using stem cells. stem cells may offer cures one day, but medical charlatans on the internet are making outrageous claims-- that they can reverse the incurable, from autism to multiple sclerosis to every kind of cancer. desperate people are being bilked out of their life's savings. as we first reported last april,

we've been looking into this surging crime, and we found there is no better window on how it works than the practice of a man who calls himself "doctor," a man named lawrence stowe. stowe has been unaware that, some of his patients have been working with "60 minutes." one of those patients is steven watters, a college administrator in lufkin, texas, who, six months before we met him, received maybe the worst diagnosis imaginable. he has a.l.s., amyotrophic lateral sclerosis, also known as lou gehrig's disease. about 30,000 americans have a.l.s. at any given time. and like watters, they all will die, most within five years, as their nervous system gradually disconnects from their muscles. >> steven watters: everything just takes a little longer. i just set things up to where it requires minimal manual effort. just handling personal hygiene

is difficult-- teeth brushing, flossing, very difficult, time- consuming. so you just make the adaptations that you can and go on. >> pelley: eventually, watters will be able to move nothing but his eyes. the same fate is ahead of michael martin, who also has a.l.s. martin has nearly lost any ability to speak, and very soon, he won't be able to walk. i wonder what it was that your regular doctor back home told you about your disease and what your prospects were. >> michael martin: he said i had about two years. >> pelley: you had about two years to live. no patient has ever been cured of a.l.s. no patient has ever seen the symptoms reversed, even temporarily. but still, desperate people find themselves drawn to a place that promotes the impossible: stowe biotherapy in la mesa,

california, near san diego, which bills itself as a "medical oasis." we asked a multiple sclerosis patient to go in with a hidden camera to hear larry stowe's pitch for his miracle treatment. that's stowe telling our m.s. patient that he can reverse her disease with his program of herbs and vitamins to boost the immune system, custom vaccines, and stem cell injections. medical experts say it's nonsense, but it's the same pitch that we secretly recorded again and again as stowe claimed to reverse cancer, a.l.s., m.s., parkinson's disease and more. >> lawrence stowe: we're the only one's who've been able to get anybody that's down here back up to here, and they stay back up to here. if we were a major pharmaceutical drug company, you know, we'd be talking about all of our research associating getting nobel prizes in medicine and things of that nature. >> pelley: larry stowe is not a medical doctor. he claims two ph.d.s, but we found he only has one, in

chemical engineering. he had a career at mobil oil and holds patents in the oil industry. but by the 1980s, stowe had taken a strange turn into pseudo-science. for a time, he promoted something called "eon water," which, he said, slowed the aging process. and by 2003, he had created the stowe foundation to advocate unproven stem cell therapies. michael martin, one of the a.l.s. patients helping with our story, had heard about stowe from a friend. and before we ever met martin, he'd already given stowe a down payment of $47,000 to start the treatment. when dr. stowe said that he could reverse this disease with stem cells, you thought what? >> martin: oh, i... i wanted to believe. >> pelley: you wanted to believe.

how does larry stowe make believers of the desperate? we wanted to see. >> stowe: steve watters? glad to meet you. larry stowe. >> stowe: nice to meet you. >> pelley: so we set up hidden cameras in michael martin's home in houston, and invited a.l.s. sufferer steven watters to pose as an interested patient. stowe came in on crutches. he's missing a leg, which he says he lost to cancer. everyone in the room knew about our hidden cameras except stowe. stowe had claimed what he called a "permanent fix" for a.l.s., so we gave watters questions to ask about stowe's therapy. >> watters: so, is there a permanent fix from the stem cells? >> stowe: oh, yes. yeah. you'll be able to... >> watters: exercise again? >> stowe: ... exercise again. oh, yeah. >> watters: well, if i opt for the permanent fix, will i avoid a feeding tube? will it keep me out of a wheelchair? >> stowe: yeah. oh, yeah, absolutely. we've gotten people out of wheelchairs. >> watters: am i going to get

closer and closer to, at some point you can say, "okay, you're cured. you're healed from this disease"? >> stowe: i believe that that is 100% possible, because we've done it with other conditions. i mean, we've done it with cancer, you know, which is just a different form of tissue destruction. >> martin: didn't your mother have cancer? >> stowe: my mother had pancreatic cancer, and we completely reversed her pancreatic cancer. she died cancer-free with a healthy pancreas. >> watters: what will it cost me for the permanent fix? >> stowe: that'll be around $125,000, because it's $50,000 for phase one; the stem cell transplant is going to run you around $25,000. and then, we do follow-up therapy after that to make sure

the results hold, and that's another $50,000. >> pelley: stowe told them they would have to travel to monterrey, mexico, for the treatment. he said his research associate there would take blood-forming stem cells harvested from umbilical cords or bone marrow, and inject those cells into their spines. those blood cells, he said, would transform into nerve or neural tissue that would reconnect with their muscles. is there a stem cell fix for a.l.s.? >> professor sean morrison: no. >> pelley: professor sean morrison is director of the university of michigan center for stem cell biology. his lab is one of the world's leading stem cell research centers. so, when stowe says he's going to take blood-forming stem cells and put them in the spinal cord to create neural cells, what do you make of that? >> morrison: you know, we study blood-forming stem cells every day in this lab, including umbilical cord blood cells. and blood-forming stem cells don't make nervous system tissue. >> watters: and then, what do

the injected stem cells do next? >> stowe: they start to regenerate your nerve tissue and repair the synapses. >> pelley: stowe's incredible pitch often works because his victims have heard something about the promise of stem cells but don't really know much about them. at one time, some scientists thought that blood-forming stem cells could replace any kind of tissue, as stowe claims. but science now knows that's wrong. stem cell therapy is the standard of care in only leukemia and certain rare diseases of the blood, nothing else. there is very early research into whether stem cells might one day help a.l.s. patients, but nothing like the claims stowe is making. dr. morrison thinks breakthroughs are years or decades away. he says stowe's claims are baseless. >> stowe: classically, people are reporting three to four weeks that they begin to notice the effects.

>> pelley: notice the effects in three or four weeks. >> morrison: you might notice side effects in three to four weeks. >> pelley: you described it as "miraculous"-- that's what it would be. >> morrison: if somebody squirted some stem cells into the spinal cord of an a.l.s. patient and they stood up out of their wheelchair and had a permanent fix, that would be miraculous. >> pelley: but that's what stowe was promising in michael martin's living room as he weaved a pitch with lies of legitimacy. >> watters: are you currently working with anybody in the f.d.a. regarding... >> stowe: oh, yeah. yeah, we... at all levels. >> pelley: even the university of texas, he said, was planning to build a research center with a particular name. >> stowe: stowe research center for regenerative medicine in affiliation with the university of texas. you can't find a surgeon in the world who doesn't support our approach. >> pelley: after hearing the pitch, steve watters and michael martin, working with us, told stowe they would go to monterrey, mexico, for the

treatment. we followed them there with hidden cameras. and we found stowe's so-called research associate. that's dr. frank morales in the dark jacket. in an email to watters, morales claimed: "we have treated well over 1,000 patients without any side effects other than positive results, which range from minimal to miraculous." but we have found that morales is improvising stem cell procedures for profit with no scientific basis. morales is an american citizen living in texas with a mexican medical license. we got the credentials he submitted to one monterrey hospital and found that the medical degree came from a caribbean school that was later shut down for selling diplomas. morales dropped out of residency training in texas. morales and stowe took our patients on a tour of the hospital where morales was already doing stem cell procedures.

he explained the techniques he uses. >> frank morales: our team will go in through a catheter and place it right up close to the brain, or will go intrathecally, you know, right into the spine, and do other things that are pretty aggressive. >> pelley: mexican officials tell us stem cell therapy for a.l.s. is not authorized. the hospital says it didn't know morales was using stem cells and wouldn't have allowed it. >> morales: so we could just go right in and, okay, you got your stem cells and you're out of here. >> pelley: we found one of morales' former patients, muna erickson, in michigan. she has multiple sclerosis, for which there is no cure. what exactly did morales tell you about what you could expect? >> keith erickson: he told me that i could expect her to be up out of the wheelchair and walking. >> pelley: she'd get out of the wheelchair? >> keith erickson: uh-huh. >> pelley: and walk away from it? >> keith erickson: uh-huh. >> pelley: erickson and her husband keith are not people with a lot of money, so in desperation, they sold their home in order to wire $15,000 to morales.

the ericksons say they arrived in a rundown mexican clinic for a scheduled spinal injection of stem cells, but morales gave her a stem cell i.v. instead. >> keith erickson: so, he ended up coming in and hanging an i.v. off the tip of her thumb that was barely viable. >> pelley: muna, show me with your hand, if you can, precisely where that i.v. went in. right at the tip of your thumb. >> muna erickson: yes. >> pelley: what did you think? >> keith erickson: i thought about taking my wife and taking her home, but she was so set on getting these stem cells, i... i think she would've had a complete mental breakdown if... had i just boarded her back on a plane. >> pelley: muna, did you get somewhat better? >> muna erickson: no, i got worse. >> pelley: back in monterrey, mexico, morales and stowe came to a hotel room, where they met patients michael martin and steve watters. they were expecting to see

another down payment-- $35,000 in cash. but that is not what came through the door. mr. stowe, mr. morales, i'm scott pelley. i'm with "60 minutes." what happened next, in a moment. >> cbs money watch update sponsored by: >> good evening. house minority leader john boehner said today he would allow tax cuts for the wealthy to expire in order to win cuts for the middle class. the new top white house economic adviser predicts unemployment will remain high. and at the box office, "resident evil: after life" clobbered the competition. i'm russ mitchell, cbs news. it every day. artg

>> pelley: steven watters and michael martin, two a.l.s. patients working with "60 minutes," traveled to monterrey,

mexico, to meet larry stowe and frank morales. stowe and morales said they could treat the symptoms of a.l.s. with an unproven stem cell therapy. they met in a hotel room that we set up with hidden cameras. stowe and morales expected to see a cash down payment of $35,000. but instead, we walked in for an on-the-record interview. that's larry stowe sitting on the right. on the couch were michael martin and steve watters. and morales was explaining how the stem cell treatment would go. hey, steve, michael. mr. stowe, mr. morales, i'm scott pelley. i'm with "60 minutes," and i'd like to ask you a few questions on the record about what you propose. i understand that you have had patients that have stood up and walked away from wheelchairs who have a.l.s. >> stowe: there have been patients that have improved to

that extent. >> pelley: you reverse the condition? >> stowe: yes. >> pelley: you know, mr. stowe, the trouble is that you're a con man. >> stowe: really? >> pelley: you're lying about this protocol. you've lied about your association with the university of texas. you've lied about your work with the f.d.a. and now, you're lying to these gentlemen about what they can expect. >> stowe: now, why do you say that? >> pelley: nobody at the f.d.a. knows anything about any of this. and the university of texas is not going to be starting a regenerative medicine clinic with your name on it. >> stowe: really? >> pelley: when we asked stowe to back up his a.l.s. claims, his story changed. give me a stowe foundation patient who has a.l.s. who has stood up out of a wheelchair and walked away. >> stowe: we don't have any a.l.s. patients; we have m.s. patients. >> pelley: we are talking about the treatment that you have taken their money for.

is that a treatment that would allow them to stand up out of a wheelchair and walk away? >> stowe: with an a.l.s. patient? no, we've done it with m.s. patients. >> pelley: i don't believe that's what they understood. >> stowe: well, then... >> pelley: i don't believe that's what you told them. >> stowe: then, they weren't listening. >> pelley: can you give me... oh, actually, we were listening very carefully. >> stowe: okay. do you have the tape recordings? >> pelley: i do. >> stowe: pull them out. >> pelley: i have. >> stowe: pull them out. i want to hear them. >> pelley: i can do that. >> stowe: okay. >> pelley: and we did. this was your meeting in houston just a few weeks ago. >> watters: well, if i opt for the permanent fix, will it keep me out of a wheelchair? >> stowe: yeah. oh, yeah, absolutely. we've had a number of a.l.s. patients be able to get out of their wheelchairs. >> pelley: that's not true, is it?

>> stowe: the stowe foundation has not. >> pelley: you told steve that you were going to keep him out of a wheelchair. that's not true, either, is it? >> stowe: no, that's very true. >> pelley: you're going to sit here after seeing that, and you're going to look this man in the face and tell him that he's going to stay out of a wheelchair. i mean, that's cruel. >> stowe: really? what is his prognosis if he doesn't do this? >> pelley: his prognosis is the same either way. >> stowe: no, it's not. >> pelley: mr. stowe, you told these men in houston that a cure was, in... in your memorable phrase, "100% possible." >> stowe: "possible." is that a guarantee? >> pelley: the folks at home are wondering what goes through your mind when one of these men pushes a suitcase full of cash across the table to you. what are you thinking?

>> stowe: i'm thinking that they came to the right place if they want any hope at all. >> watters: so, is there a permanent fix from the stem cells? >> pelley: many patients have pinned their hope on dr. frank morales and his improvised stem cell procedures. recently, he injected stem cells into the spine of a seven-year- old american boy in an attempt to treat the boy's autism, a procedure with no basis in medical science. we found morales' training is dubious. this is the certificate he presented to a monterrey hospital, showing he completed his training at texas tech university. but in the interview, he switched schools. have you ever been licensed to practice medicine in the united states? >> morales: i have, and i worked under the university of texas, where i was at... at el paso and came to mexico after that. >> pelley: the university of texas, el paso, has no medical school and no record of morales as a student. but you have a license, or had a

license to practice in the state of texas? >> morales: absolutely. it was an institutional license at the university of texas, el paso-- utech, utep-- so you can go there, you can find it. i mean, that's simple, if you did your homework. that's lousiness, i mean, on your behalf, i'm sorry to say. >> pelley: not only does he have no credentials from the university of texas, we found that his texas tech credentials are fraudulent. a texas tech lawyer told us: "where it was obtained or manufactured i couldn't say, but it was not issued by texas tech." several minutes into the interview, we watched the stowe- morales relationship dissolve. morales walked out, then came back to disavow stowe. >> morales: scott, scott. yeah, you know, i think that just in the sense of... of using, you know, his... you know, using him to try to bring me down, i think that that is inappropriate. >> pelley: well, sit down and talk to me about it. legal experts tell us that both stowe and morales have broken

u.s. law, committed fraud, by making a false claim. it doesn't matter that the procedure is done in another country. we wondered why the f.d.a. is not acting against the many stem cell con artists whose web sites are up for anyone to see. but the f.d.a. commissioner, margaret hamburg, declined to talk with us on camera about any aspect of stem cell quackery. many experts believe that the f.d.a. is outmatched. >> larry goldstein: patients need to beware. >> pelley: larry goldstein, a prominent stem cell biologist, and researcher doug sipp, are with the international society for stem cell research, an organization of the world's leading stem cell scientists. sipp is tracking bogus stem cell clinics all around the world. how have these operations grown, say, in the last five years or so? >> doug sipp: i would say the growth has been explosive. i've been tracking it closely for the past three years, and i've been able to come up with more than 200 clinics that are offering some version of stem

cells for some type of medical condition for which there is no really good evidence that the stems would be either safe or effective. >> pelley: well, are all of these clinics frauds? >> sipp: on one end of the spectrum, you have people who are doing, essentially, badly designed, uncontrolled human medical experiments for profit. and then at the other end of the spectrum, you just have thieves who are preying on the sick and their families. >> goldstein: now, an a.l.s. patient might say to you, "how could i possibly be worse?" this is the question you get sometimes. "how could i possibly be worse?" >> pelley: "i'm going to die. why not give it a try?" >> goldstein: "i going to die in two or three years. why not give it a try?" well, what if, as a result of this treatment, you ended up in excruciating pain? what if you managed to bankrupt your family through the use of one of these expensive, unauthorized treatments so they can't care for you properly as you decline? there are things that are worse than your current situation, i think. >> pelley: the experts in stem cell research believe these

procedures are at best ineffective and potentially dangerous. a study by u.c.l.a. found patients at a chinese clinic often developed spinal meningitis. but there's rarely any mention of risk on the web sites that offer false hope for dozens of afflictions, ranging from down syndrome to cancer. >> sipp: one of the different things now is the power of the internet now gives just tremendous global reach to people who, in the past, would be kind of the local quack. >> pelley: so, instead of the snake oil salesman standing in the back of a pickup truck, he can now reach every a.l.s. patient on earth. >> sipp: and say, "come to me, and i'll help you out in mexico, or in russia, or in thailand." >> pelley: what we see here, essentially, is stowe on an industrial scale. >> goldstein: stowe on steroids. >> sipp: yeah, you could say that. >> goldstein: he might as well be sticking his hands into the pockets of those people and taking the money out without even talking to them. that's how bad i think it is. >> pelley: i wonder what you think when the top people in the field that you pretend to work

in call you a "snake oil salesman." >> stowe: comes with the territory. >> pelley: it does come with the territory. we wondered what stowe would say to the idea of giving michael martin his $47,000 back. >> stowe: has he asked for it? >> pelley: i'm asking. >> stowe: we'd give it back to him. >> pelley: now, that's a deal i'd like to make. >> stowe: really? okay. and when he continues to go downhill six months from now and hasn't made any progress, are you going to cover the cost of his care? >> pelley: i'm not buying what you're selling. >> stowe: fine. >> pelley: of course, that refund never came. when we first walked into the interview, we thought stowe might not stay. but he sat there for two hours as though, if he only talked long enough, he'd convince us. thanks for sitting with us and talking to us. >> stowe: now, you're not running away on me, are you?

>> pelley: well, i was planning on leaving, yes. >> stowe: okay. >> pelley: i think i'm done. >> stowe: all right. >> pelley: thank you. >> stowe: you just cost this man his life, i want you to know that. >> pelley: you know, i don't think so. larry stowe never gave up, even after his lies were exposed. when we left the room, he turned to a.l.s. patient michael martin and tried to close the sale. >> stowe: we'll keep in touch, because i can tell you-- you know what's going to happen if you don't take some type of aggressive action. >> pelley: the scene at the hotel was the end of the stowe/morales collaboration. they didn't contact the patients again. michael martin and steve watters continued to fight the progression of a.l.s. what would you like to see happen to larry stowe? >> martin: i... i don't care, >> pelley: "i don't care," martin said. >> martin: he has to live with

himself. >> pelley: "he has to live with himself." since our story first aired in april, lawrence stowe has closed his business in san diego. we've learned that the f.d.a. has been investigating stowe and morales, but the agency won't comment. meanwhile, the a.l.s. patients who helped us with our story are losing ground to their incurable disease. steve watters had to retire from the college. and michael martin can no longer walk and is now on a feeding tube. what's around the corner is one of life's great questions. and while it can never be fully answered, it helps to have a financial partner like northern trust. by gaining a keen understanding of your financial needs, we're able to tailor a plan using a full suite... of sophisticated investment strategies and solutions. so whatever's around the corner can be faced with confidence.

michael jackson, i'm like, "oh, my god." the second i got on the stage, i just opened up and i became this whole other person on the stage. and i wanted to do it every day all day. >> kroft: with her best friend, kelly rowland, and two other pals from houston, they began winning talent contests. by the time they were 16, the quartet had morphed into destiny's child, one of the most successful pop groups of the '90s. ♪ home-schooled, under-aged, and traveling with her parents on the road, beyonce skipped the boys and the after-parties, and passed the time on the tour bus with the other girls reading the bible. >> beyonce: we were nice ladies. i mean, i'm not saying that we were perfect teenagers. but, we were... we were raised well and, honestly, we were too busy to... trying to be superstars. we didn't even have time to think about it, honestly. lord god, we thank you for this day. >> kroft: there's still a prayer

before every show. but since beyonce began her own solo career eight years ago, a lot of things have changed. she has a successful clothing line with her mother, lucrative cosmetics deals with l'oreal and coty, and an estimated income last year of more than $80 million. she has graced the cover of more than 200 magazines. and that shy girl from houston who was a late bloomer in terms of her own sexuality has obviously been a quick study. parts of her show would make a preacher blush. ♪ you have a really sort of clean- cut, wholesome reputation. and then, out there on the stage, you're a seductress. >> beyonce: okay. thanks. ( laughs ) i'll take that. >> kroft: you're seducing the audience. >> beyonce: really, i don't think about it too much. i'm just free, and i can express my sensuality. i can express my pain,

vulnerability, my strength, all of those things. >> kroft: where did you learn all that stuff? >> beyonce: well, just because i had a sheltered upbringing doesn't mean i haven't been a woman. i'm a woman that has had life experiences. ( laughs ) >> kroft: she is also a married woman now-- which we'll get to in a minute-- and a worldly one, having seen most of it several times over. this last tour took her to 12 countries and 66 cities for 110 performances, including six sold-out concerts in dublin. >> beyonce: so, that's a huge, huge accomplishment for me, especially being an african- american singer. there's not many of us that can sell out these venues. ♪ >> kroft: but her crossover appeal is by no means limited to white audiences. the reception was the same in japan and korea, in india, and even the middle east. >> beyonce: when i was in egypt, i was riding in the cars, and i had the window just down to

here, so i could look outside and see this beautiful place. and everyone was recognizing this. and i'm like, "oh, my god, this is crazy. in egypt?" and it's just... music is so powerful, you know? there were women in burkas full out, singing ♪ "to the left, to the left." >> ♪ to the left, to the left... >> kroft: her fan base is largely women. they are drawn to her songs about everyday problems like boyfriends and breakups, and she is both a messenger and a symbol of female empowerment-- glamorous, sexy, willful and strong. ♪ ♪ ♪ ♪ ♪ ♪ >> beyonce: these two hours on the stage every day is what i was born to do. it's why i'm here.

♪ >> kroft: while her career is still managed by her father, beyonce is the steam that drives the engine of this huge enterprise: 18 truckloads of gear, a family of 150 employees, many of them who have been with her for nearly a decade and a few since she was 12. the production costs on the road are more than a million dollars a week. that's a lot of responsibility for... >> beyonce: for one woman. >> kroft: ... for one woman. >> beyonce: it is. but, you know, i... i put a lot into this show. i don't... i don't give half of anything; i give 100%. and it has to work every night. so... and when it doesn't... ( laughs ) when it doesn't, i'm not too happy. >> kroft: you're not too happy? >> beyonce: no, no. it just doesn't feel like what i want it to feel like. it's difficult, at times, because i am really critical. i have to be boss at one moment, and then the next moment, i'm,

you know, me. >> kroft: have you always been a type-a personality? >> beyonce: i think so. yes. i'm absolutely... >> kroft: assertive. >> beyonce: very assertive. >> kroft: you got the last word. >> beyonce: the first and the last. ( laughs ) >> kroft: she says her top priority is to make sure that the concert audience always gets its money's worth, even if it means putting herself at some personal risk. >> beyonce: the first time i was on that trapeze, i was a little afraid, like, "am i really going to do this every night?" but i feel safe now. some nights, i do two or three spins, and some nights, i do 20 spins, depending on how adventurous i'm feeling. >> kroft: but perhaps the most dangerous thing she does is to perform all those dance routines in five-inch stiletto heels. this rehearsal was shot by her private videographer, who records many of her off-stage activities for documentaries and dvds. she is very much the custodian of her own image, and this

allows her to guard her privacy, keep outside camera crews and paparazzi at a distance, and control content for her own commercial use. she is particularly protective of her relationship with her husband, hip hop superstar jay- z. this short backstage clip was provided to us, but you are more likely to see bigfoot than either of them sitting down to discuss their marriage. we gave it a try, but we couldn't even get her to mention his name. who's the most important person in your life? >> beyonce: it's not just one person. but, i guess, it should be me. it should be me. just start with me. >> kroft: is your husband comfortable living with somebody as competitive and as ambitious as you are? >> beyonce: i... you're going to have to ask my husband, but i think so. i'm not... i'm competitive, really, with myself. i'm not a competitive person that walks in thinking about other people and how i can compete with them, or especially not my husband. not at all.

>> kroft: do you talk shop? >> beyonce: do i talk shop with my husband? what does... what does he mean? >> kroft: talk about the business, talk about performing. >> beyonce: we talk about everything. ( laughs ) >> kroft: one last question. >> beyonce: okay, is it about... >> kroft: who has the bigger ego? >> i don't know. we don't really have egos. it's not about ego. i think it's appropriate for the stage. it's appropriate for certain moments, but egos are not attractive. ♪ >> kroft: we didn't see any evidence of hers in dublin. when it came to evaluating her own talents and future prospects, she was remarkably humble. >> beyonce: what i love the most is singing. if i had to say, "okay, if you couldn't dance, if you couldn't do a movie, if you couldn't..." and i'd probably just stand there and sing, if i had to choose. ♪ >> kroft: you get the sense that, whatever happens to

musical styles and tastes, beyonce will adapt. she has the ability to take a blues classic like "at last" and make it her own. ♪ ♪ ♪ >> kroft: before she sang it to the obamas at the inaugural ball for their first dance in the white house, she'd sung it in the film "cadillac records," in a role she put on 20 pounds for to portray the tortured, drug- addicted etta james, who made the song famous. her performance won her the best reviews of her young movie career that's ranged from a comedy turn in "austin powers' goldmember" to a leading role in "dreamgirls." ♪ she says she wants to try and model her career after one of her idols, barbra streisand,

another singer turned actress and director. >> beyonce: i know that she does everything, and i know that it's all barbra streisand. it's not someone that's telling her what to do, what to wear, what to sing-- it's her. and i respect those types of artists. >> kroft: is it true that you run on a treadmill with a big picture of a... of an academy award in front of it? >> beyonce: i do. but it's not right in front of the treadmill, it's over in the corner somewhere. just so it's in the back of my mind. >> kroft: not quite the back, i'll bet. i bet it's a little closer than the very back of your mind. >> beyonce: well, it's getting closer. >> kroft: where does all this ambition come from? >> beyonce: i don't know. i always wonder myself, "what am i trying to prove?" like, "what is this?"

>> safer: now, andy rooney. >> rooney: i keep reading about the problems people have falling asleep and staying asleep nights. an organization called the national sleep foundation did a study, and it says the economy is making people sleepless. wouldn't they just? i feel for all those people who aren't sleeping, but not sleeping is not my problem. i can sleep night or day, sitting, standing or lying down. i often fall asleep right here at this desk. last week, i took a bus cross- town in new york city and went six blocks past my stop because i fell asleep. someone took a poll several years ago that reported on what time americans go to bed every night and how many hours sleep they get. the poll showed that we sleep eight hours a night, which was no surprise to me, but i think i can get along on seven hours, though. i can take eight, but anyone who

gets nine hours sleep is sleeping his life away. if you figure out how much sleep you're going to get overall in your life, it's really depressing. we all sleep away about a third of all the hours we have to live. now, how in the world did we let that happen? i suspect we all get more sleep than we need. what we need is some kind of a gauge, like a thermometer, that would tell us when we need more sleep and when we've had enough. never mind the alarm clocks. when the battery on some gadgets needs charging, a red light comes on or a bell rings. we should all have something like it that would let us know when we've had enough sleep. i'm lucky, because i'm a very quick sleeper and i can sleep anywhere. some of the best sleep i've ever had has been in movie theaters during bad shows or in front of the television set. i try to go to bed early saturday night so i don't fall asleep during the football game sunday or while i'm on "60

minutes." i hate it when that happens. >> safer: i'm morley safer. we'll be back next week with another edition of "60 minutes."
